When I post Q here, this error message is pop up without telling me the details: "Please enter the required fields."

I tried to post Q several times here. But the following error message is popped several times without indicating exact which field is required and empty, and this message prevented me to post my Urgent Q on IBM Watson API.

Please enter the required fields =====================.

This Q & A service really needs to be updated and improved, so that this will not waste lots of time of your IBM product users.

It seemed like I was getting that "Please enter the required fields" error because Watson was disagreeing with my tag choices. So, i tried from my laptop and at home on a slower DSL connection and picked simpler one word tags and it didn't change the tags. Also the network for IBM was MUCH busier. (occasional web pages saying system was offline, but you could reload and it was back again) However I noticed the captcha process was out of synch and would give a check mark with pictures shown or picked. Then, it finally posted my question without error....but then get a double posting and show me asking two questions when i'd only asked that one. The double posting like that is what i've seen when social media uses NoSQL databases to handle heavy loads but then the multiple servers involved get temporarily out of synch.... you see a double post of your comment, or it might disappear...and may or may not come back for viewing. Watson process synch, captcha process synch and NoSQL database tendencies are causing that "Please enter the required fields" stray error.....I think
